VACUUM-CLEANER BRUSH.

Application-filed August 80, 1926. Serial No. 132,427.

T his invention relates to brushes for suction cleaning nozzles and more particularly to a brush arranged to be mounted upon the outside of the nozzle parallel to one lip detached from the nozzle.

The object of the improvement is to provide a cleaning nozzle with an unobstructed opening, a brush being detachably mounted upon the-outside of the nozzle adjacent and parallel to one lip thereof, and arranged to be easily and readily detached from the nozzle when it is desired to use the cleaner without the brush.

The above and other objects may be attained by constructing the nozzle and brush in the manner illustrated in the accompanying drawing in which Figure 1 is a plan View of the nozzle portion of a vacuum cleaner provided with the improved brush;

Fig. 2, a front elevation thereof;

Fig. 3, a transverse section through one end portion of the nozzle'and brush taken sub-' stantially on the line 33, Fig. 1; and

Fig. 4, a detached perspective view of one of the spring attaching arms for the brush.

similar -numerals refer to similar parts throughout the drawing. Y

The vacuum cleaner upon which the brush is illustrated includes the fan casing lhaving the outlet neck 2, the nozzle 3 communicating with the inlet side of the fan casing and having the elongated mouthportion 4 7. supported as by the casters 5 for to and fro movement upon the floor. I

For the purpose of taking up thread, lint and similar loose material from the carpet or other surface to be cleaned, it is desirable to provide the nozzle with a disturbing device, such as a brush, to engage and loosen the threads or other material from the surface being cleaned.

Such device is preferably located outside of and adjacent to one side of the nozzle in order that'an unobstructed nozzle opening be provided and, furthermore, to permit use of a very narrow mouth upon the nozzle in order to provide the greatest amount of suction.

The brush comprises the straight bar 6, preferably of wood, and reinforced upon its "brush extending around the ends of the nozfront and top faces with a steel angle strip 7, and provided on its under side with a straight row of bristles 8.

A substantially U-shaped angular spring attaching arm 9 is connected to each end portion of the brush as by rivets 10 and extends around the end of the nozzle and is provided near its free end with a notch ll arranged to receive the rearwardly disposed screw stud 12, fixed upon the rear side of the nozzle month, near the end thereof.

A thumb nut 13 is provided upon each of these screws whereby the brush may be easily and readily clamped in place with the straight row of bristles 8 adjacent to and parallel with the forward Ii 14 of the mouth of the nozzle. When it is esired to remove the brush it is only necessary to loosen the thumb nuts 13 and'disengage the notches 11, of the U-shaped arms, from the screws 12.

With this construction the brush may be firmly held in the operative position in sweeping contact with the floor, as the cleaner is moved to and fro thereon, producing a vigorous brushing action upon the objective surface and disturbing and loosening threads, lint and other material which may have a tendency to adhere to the surface being cleaned.

I claim:

1. The combination with a suction cleaner nozzle having an elon ated mouth, of a straight brush located ad acent to and spaced from one side of said nozzle, angular arms upon the ends of the brush extending around the ends of the nozzle and means for attaching said arms to the opposite side of the nozzle.

2. The combination with a suction cleaner nozzle having an elongated mouth, of a straight brush located adjacent to and spaced from one side of said nozzle, an ular spring arms upon the ends of the brus extending around the ends of the nozzle and means for attachin said arms to the opposite side of the nozz e. i I

3. The combination with a suction cleaner nozzle having an elongated mouth, of a straight brush located at one side of said nozzle, angular arms upon the ends of the zle, one end of each of the arms being provided with a notch, studs upon Hm onnosite side of the nozzle for engagement in said notches, and means on said studs forclamping the arms upon the studs.

4. The combination with a suction cleaner 5 nozzle having an elongated mouth, of a straight brush located at one side of said nozzle, angular arms upon the ends of the brush extending around the ends of the nozzle, one end of each of the arms being provided with a notch, studs upon the oppo- 1 site side of the nozzle for engagement in said notches, and nuts upon said studs for clamping the arms upon the studs.

In testimony that I claim the above, I have hereunto subscribed my name.
